Official summary

Dealer Message - On February 18, 2021, American Honda announced a warranty extension for certain 2019-2020 RDX vehicles. This warranty extension covers communication issues in the MOST bus network where the vehicle may experience popping or crackling from the speakers, a blank display, no sound from the audio system, a Network Loss message, center display staying on after turning the vehicle to the OFF mode with the door open, display switches between the Day Mode and Night Mode, the "Drive mode not available" message appears, or the disclaimer message is stuck on.

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
